The JTAG specification, IEEE 1149.1, recommends that JTAG_TMS should be held at 1 while the signal applied at JTAG_TRST_N
changes from 0 to 1. Otherwise, a race may occur if JTAG_TRST_N is deasserted (going from low to high) on a rising edge of JTAG_TCK
when JTAG_TMS is low, because the TAP controller might go to either the Run-Test/Idle state or stay in the Test-Logic-Reset state.

Recommended Operating Supply Voltages
Absolute Maximum Voltage Rating
Warning: For proper and reliable operation in adherence with this data sheet, the device should not exceed the recommended operating voltages
in Table 13. The absolute maximum operating voltages in Table 14 are offered to provide guidelines for voltage excursions outside the recommended
voltage ranges. Device functionality is not guaranteed at these conditions and sustained operation at these values or any exposure to voltages outside
the maximum range may adversely affect device functionality and reliability.

Power-Up Sequence
This section describes the sequence in which various voltages must be applied to the part during power-up to ensure proper functionality. For the
PES16H16, the power-up sequence must be as follows:
1. V
DD
I/O — 3.3V
2. V
DD
Core, V
DD
PE, V
DD
PEA — 1.0V
3. V
TT
PE — 1.5V
When powering up, each voltage level must ramp and stabilize prior to applying the next voltage in the sequence to ensure internal latch-up issues
are avoided. There are no maximum time limitations in ramping to valid power levels. The power-down sequence must be in the reverse order of the
power-up sequence.
Recommended Operating Temperature
Power Consumption
Typical power is measured under the following conditions: 25°C Ambient, 35% total link usage on all ports, typical voltages defined in Table 13
(and also listed below).
Maximum power is measured under the following conditions: 70°C Ambient, 85% total link usage on all ports, maximum voltages defined in
Table 13 (and also listed below).
